DETAILED DESCRIPTION

The detailed description of exemplary embodiments herein makes reference to the accompanying drawings, which show exemplary embodiments by way of illustration and their best mode. While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the inventions, it should be understood that other embodiments may be realized and that logical, chemical and mechanical changes may be made without departing from the spirit and scope of the inventions. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation. For example, the steps recited in any of the method or process descriptions may be executed in any order and are not necessarily limited to the order presented. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step. Also, any reference to attached, fixed, connected or the like may include permanent, removable, temporary, partial, full and/or any other possible attachment option. Additionally, any reference to without contact (or similar phrases) may also include reduced contact or minimal contact.

In various embodiments, a firearm may comprise a firearm firing mechanism configured to activate firing of ordnance. Such firearms can comprise a firing direction F (e.g., a forward direction) that represents the direction of travel of ordnance fired from the firearm.

With reference to FIGS. 1-4, a firearm firing mechanism (“mechanism”) 100 (e.g., trigger mechanism, trigger module, trigger assembly, and/or the like) in accordance with the present disclosure is illustrated. Mechanism 100 may comprise a firing mechanism housing 112. In various embodiments, mechanism 100 may comprise a sear 102 at least partially disposed within said housing. Sear 102 can comprise, for example, a member configured to pivot around a point within housing 112.

In various embodiments, mechanism 100 comprises a sear activating spring 108. In such embodiments, spring 108 is disposed at least partially within housing 112, and is configured to rotate sear 102. For example, a force may be applied to spring 108. When the tension is released, spring 108 can rotate sear 102.

Mechanism 100 can further comprise, for example, a disconnect 104. In various embodiments, disconnect 104 is at least partially disposed within housing 112, and is configured to engage with sear 102. For example, sear 102 can be rotated against spring 108 to cause spring 108 to exert a force on sear 102. In such configurations, disconnect 104 can engage and retain sear 102, allowing spring 108 to maintain a force against sear 102. Disconnect 104 can then be released from engagement with sear 102, allowing spring 108 to rotate sear 102. Moreover, mechanism 100 may comprise any suitable structure configured to actuate a sear form a non-firing to a firing position (e.g., fire ordnance) in response to being actuated.

In various embodiments, mechanism 100 can further comprise a trigger component 106 (e.g., trigger shank). Trigger component 106 can, for example, be coupled to disconnect 104. In such configurations, trigger component 106 can be manually activated, causing disconnect 104 to be released from engagement with sear 102 and allowing sear 102 to be rotated by spring 108.

Trigger component 106 can comprise a first profile 110 (e.g., a first portion, a first surface, a first segment, and/or the like) and a second profile 114 (e.g., a second portion, a second surface, a second segment, and/or the like). In various embodiments, first profile 110 and second profile 114 of trigger component are different from each other. Moreover, the position of second profile 114 (e.g., the location of second profile 114 relative to the operator, the trigger guard, and/or the rest of the firearm) may be a function of the shape, geometry and/or angle of first profile 110. For example, as illustrated in FIGS. 1-4, first profile 110 can comprise a portion of trigger component 106 which extends from housing 112. In various embodiments, first profile 110 extends at an angle between about zero and about 180 degrees from a lower surface 122 of lower receiver 120, in which mechanism 100 is installed. More specifically, the angle may be between approximately 60 degrees and 120 degrees. In various embodiments, first profile 110 can be oriented away from the firearm operator.

In various embodiments, second profile 114 (e.g., engagement portion, finger pad portion, pull portion, and/or the like) may comprises a curved shape and/or contoured shape. As illustrated in FIGS. 1-4, second profile 114 can comprise a curved shape that curves away from the firing direction F. In various embodiments, second profile 114 can be curved toward a firearm operator.

In various embodiments, second profile 114 can comprise a curve that is generally compatible and/or ergonomic to a human figure. For example, second profile 114 can comprise a curve or curved section that corresponds to the degree of curvature of an exemplary human finger. In such embodiments, a firearm operator can activate trigger component 106 without directly contacting the portion of trigger component 106 comprising first profile 110. Instead, activation of trigger component 106 can be achieved solely through contact with the portion of trigger component 106 comprising second profile 114.

In various embodiments, second profile 114 may be an engagement portion. The engagement portion may be formed in and/or operatively coupled to trigger component 106. The engagement portion may be configured to receive an input form an operator. The input may be conducted from second profile 114 (e.g., the engagement portion) through trigger component 106 to mechanism 100.

In various embodiments, trigger component 106, and more specifically, the position and orientation of second profile 114 may provide a uniform, repeatable engagement point for the user. In contrast, a user may engage a traditional trigger at any point along the trigger profile created a non-uniform trigger pull for the user. By making the engagement point (e.g., second profile 114) uniform in shape and relative location to an operator, the amount of force associated with a trigger pull may be constant. In this regard, the operator is able to engage mechanism 100 at a specific engagement point (e.g., second profile 114). The force associated with the trigger pull may be adjusted by adjusting the geometry of trigger component 106 (e.g., by replacing a first trigger component 106 with a first overall profile with a second trigger component 106 having a second overall profile) and/or other components in mechanism 100 (e.g., springs).

In various embodiments, a trigger may comprise a front surface trigger component profile having an upper portion 110, a transition point 113, a lower portion 114, and an end 115. A first radius of curvature of upper portion 110 may be different than a second radius of curvature of the lower portion 114. Transition point 113 may be the point at which the front surface trigger component profile transitions from the first radius of curvature to the second radius of curvature. In various embodiments, the lower portion 114 may have a length that is defined between transition point 113 and end 115. This length may be suitable sized for engagement by a human finger and/or two human fingers. For example, this length may be for example, approximately 0.5 inch (approximately 1.2 cm) to approximately 2.5 inches (approximately 6.35 cm).
